Deformation of breast masses between supine ultrasound and prone magnetic resonance imaging.

Deformation of breast masses between supine ultrasound and prone magnetic resonance imaging. Acta Radiol. 2019 Feb 06;:284185118824758 Authors: Yoshida M, Goto M, Sakai K, Kiba M, Nagano H, Yamada K Abstract BACKGROUND: Breast masses will deform between different postures and modalities in the background mammary gland. However, this difference in deformation between benign and malignant masses has not been studied. PURPOSE: To investigate the feasibility of using the change of the longitudinal-transverse ratio (L/T) of a breast mass from supine ultrasonography (US) and prone magnetic resonance imaging (MRI) as representing deformation in differentiating between benign and malignant masses. MATERIAL AND METHODS: The participants were 197 consecutive patients with 201 breast masses (55 benign, 146 malignant) who had undergone both US and MR examinations with histological diagnoses at our hospital from January 2012 to December 2014. On US, the largest transverse diameter of the mass (TUS) parallel to the pectoral muscle and the longitudinal diameter (LUS) perpendicular to the muscle were measured. On prone MRI, the largest transverse diameter of the mass (TMR) parallel to the pectoral muscle and the orthogonally oriented diameter as the longitudinal direction (LMR) were measured. The change of the L/T between these modalities was compared between benign and malignant masses. RESULTS: Malignant breast masses showed significantly smaller change...

In this study, we compared different anesthesia and operation methods for modeling VX2 hepatocarcinoma in rabbits. Forty New Zealand white rabbits were randomly divided into three groups: A, B, and C. Group A underwent ultrasound-guided implantation and intravenous anesthesia; Group B underwent ultrasound-guided implantation and inhalation anesthesia; Group C underwent laparotomy implantation and intravenous anesthesia. Anesthesia and operation differences were compared between groups A and B, and A and C, respectively. We used magnetic resonance imaging (MRI) to assess tumor formation and growth, and pathological examinat...

ConclusionWith the proper technique and knowledge of the ankle anatomy, high-frequency US proved to be an effective imaging modality in the diagnosis of CFL lesions in chronic lateral ankle injuries. US had a high sensitivity and specificity in the evaluation of the CFL when MRI findings were regarded as the reference standard.

Recently revised international guidelines for hepatocellular carcinoma (HCC) suggest that selected patients with inadequate surveillance ultrasonography to be assessed by alternative imaging modalities such as computed tomography or magnetic resonance imaging (MRI). MRI with contrast material has drawbacks associated with the use of gadolinium contrast agent. Non-enhanced MRI consisted of diffusion-weighted imaging and T2-weighted imaging showed significantly better performance than ultrasonography as a surveillance tool for HCC in a high-risk prospective cohort. The estimated scan time of non-enhanced MRI was less than 6 ...

CONCLUSIONS: At the moment, we are uncertain whether rotator cuff repair surgery provides clinically meaningful benefits to people with symptomatic tears; it may provide little or no clinically important benefits with respect to pain, function, overall quality of life or participant-rated global assessment of treatment success when compared with non-operative treatment. Surgery may not improve shoulder pain or function compared with exercises, with or without glucocorticoid injections. The trials included have methodology concerns and none included a placebo control. They included participants with mostly small degenerativ...

This study aimed to investigate the safety and efficacy of MRgFUS for PD by systematically reviewing related literature. PubMed and EMBASE were searched to identify related studies. Inclusion criteria were (1) reported the efficacy or sa fety of MRgFUS for PD and (2) published in English. Exclusion criteria were (1) nonhuman study, (2) review or meta-analysis or other literature types without original data, and (3) conference abstract without full text. Data on study characteristics, treatment parameters, efficacy, and adverse event s were collected. Descriptive synthesis of data was performed. Eleven studies containing 80...

CONCLUSIONS: This smartphone application coupled with targeting device can be used in various settings such as EVD placement in hydrocephalus and in other brain targeting candidates in emergency settings. Also, it may be used in any emergency or neurosurgery department centers with no access to advanced neuro-imaging facilities, only using patient's simple cranial measures to achieve acceptable and highly accurate brain targeting compared with conventional, time consuming and costly techniques. We plan to expand this study to clinical trials for further evaluation. PMID: 31802048 [PubMed - in process]

Authors: Ji X, Zhou S, Yang P, Liu F, Li Y, Li H Abstract Ultrasound (US) combined with magnetic resonance imaging (MRI) in the diagnosis of primary hepatocellular carcinoma (PHCC) and recurrent hepatocellular carcinoma (RHCC) were compared. The clinical data of 329 patients with hepatocellular carcinoma (HCC) admitted to Qingdao Women and Children's Hospital from June 2015 to December 2017 were collected. One hundred and sixty patients with PHCC were regarded as the PHCC group, and the other 169 patients with RHCC were regarded as the RHCC group. US and MRI were used in the imaging diagnosis of both groups and the...

Prenatal risk assessment of congenital diaphragmatic hernia (CDH) relies on prenatal ultrasound (U/S) and fetal magnetic resonance imaging (MRI). When the modalities differ in prognosis, it is unclear which is more reliable.

Astley, D.Gareth EvansAbstractThe incidence of breast cancer continues to increase worldwide. Population-based screening is available in many countries but may not be the most efficient use of resources, thus interest in risk-based/stratified screening has grown significantly in recent years. An important part of risk-based screening is the incorporation of mammographic density (MD) and single nucleotide polymorphisms (SNPs) into risk prediction models to be comb...

Abstract OBJECTIVES: To estimate the impact of peri-prostatic fat (PPF) measurements using preoperative magnetic resonance imaging on the prediction of prostate cancer (PCa) with transrectal ultrasound-guided biopsy. PATIENTS AND METHODS: We performed a retrospective 2-center study on 660 consecutive patients receiving transrectal ultrasound-guided biopsy-biopsy from June 2016 to October 2018. Pathologic and immunohistochemical characteristics were collected. PPF measurements including PPF area (PPFA) and PPFA to prostate area (PA) ratio (PPFA/PA) were assessed by preoperative staging magnetic resonance imagi...
